REVERSING MECHANISM FOR ENGINES.

Specification of Letters Patent.

Patented. Dec. 5, 1916.

Application filed April 26, 1916. Serial No, 93,707

To all whom it may concern .1

Be it known that I, WARREN WAGNER, a citizen of the United States, residing at Strawn, in the county of Palo Pinto and State of Texas, have invented certain new and useful Improvements in Reversing Mechanism for Engines, of which the following is a specification, reference being bad to the accompanying drawings.

This invention relates to certain improvements in reversing mechanism for engines, and it is an object of the invention to provide novel and improved means whereby the operating lever may be supported in such a manner as tosubstantially eliminate lost motion, and whereby the reverse lever may be operated with greater convenience and facility.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved reversing mechanism whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view. in elevation illustrating a reversing mechanism for engines in applied position, the coacting engine being diagrammatically disposed and with parts omitted; Fig. 2 is an enlarged view in top plan of the rack as herein embodied with the lever and coacting link shown in section; Fig. 3 is a fragmentary view in top plan of the intermediate portion of the link, the coacting lever being shown in section; and Fig. 4 is a fragmentary enlarged view partly in elevation and partly in section illustrating the operative connection between the outer end portion of the link and the rack.

As disclosed in the accompanying drawings, F denotes the frame of a vertical engine and wherein the controlling valve within the chest C is under control of the block 3 arranged in a conventional manner within the arcuate guiding slot S.

Secured to the frame F at a predetermined point below the slot S is an extremity of the link L, the inner end portion of said link L, as at 1,;being horizontally directed with its intermediate portion 2 inclined downwardly on a predetermined angle and having its outer end portion 3 disposed down-' wardly on a predetermined angle relative to the intermediate portion 2, the angle of the portion 3 relative to the portion 2 being greater than the angle of the portion 2 relative to the portion 1.

R denotes a rack comprising two lengths of metal, one end portion 4 of one of the lengths being twisted substantially to 90 in order to overlie the upper face of a sh0ulder 5 included in the frame F adjacent the lower end thereof, and said portion 4i is suitably connected to the shoulder 5, as indicated at 6. The vertical portion of the length of material is arcuate in form and has its under edge provided with the notches 7 for a purpose which will hereinafter be self-evident.

The second length of material is arranged at one side of the first named length and is also arcuate in form and has its inner extremity inwardly offset, as at 8, to afiord a foot contacting with the first named length outwardly of its twisted portion 4, and suitably secured thereto, and interposed between said lengths of material at a point inwardly of the outer ends is the block 9 whereby said lengths of material are arranged in predetermined spaced relation. The under edge of the second length of material is also provided with notches 10 in transverse alinement with the notches 7 of the arcuate portion of the first named length.

The free or lower extremity of the portion 3 of the link L is offset, as indicated at 11, and is adapted to be inserted between the free extremities of the lengths of material as comprised in the rack R in advance of the interposed block 9 with the inner edge thereof contacting with the outer face of the block.

The intermediate portion 2 of the link L has secured thereto the strap 12 with its intermediate portion offset and disposed between the strap 12 and the intermediate portion 2 is the reversing lever 14:, said lever 14 being pivotally supported intermediate its length by the bolt 15 passing freely through the lever 14 and operatively engaged with the intermediate portion 2 of the link L and the strap 12. The upper extremity of the reversing lever 14 is operatively engaged, as at 16,,in a conventional manner with the block B.

The lower extremity of the lever 14: extends between the ar'cuate portions of the lengths comprised in the rack R and the portion of the lever therebeneath is provided with the conventional latch 17 adapted to coact with the notches l0 hereinbefore referred to and for a purpose which is be lieved to be clearly apparent to those skilled in the art to which my invention appertains.

It has been fully demonstrated in practice that with a reversing lever mounted as hereinbefore set forth, lost motion is substantially entirely eliminated and the lever can be operated with greater convenience and facility especially in view of the fact that the rack It coacts with the lower end. portion of the lever 14, and thereby assures the same traveling in substantially a fixed spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

In combination with a vertical frame and a movable body carried thereby, a link secured to one face of the frame and extending therebeyond, the extended portion of the link comprising two downwardly disposed and angularly related portions, said link being secured to the frame at a point below the movable member, an arcuate rack secured at one end portion to the frame and at its opposite end portion to the outer end of the link, a lever pivotally engaged intermediate its length with the inner extended portion of the link the upper end of said lever being operatively engaged with the movable member, said link extending below the rack, a latch mechanism carried by the lever below the rack immediately adjacent thereto and coacting with the rack, and means carried by the rack and coacting with the lever for holding said. lever against movement in a direction away from the rack.

In testimony whereof I hereunto affix my signature in the presence of twowitnesses.
